'llie deric lieiein shown comprises a boiler portion A, a tank portion B, and a fuel supply and control portion C.

The boiler portion A comprises a plurality a pair of like end sections 12. Each of these sections 11' and 12 is provided with two vertical passa-ges 13 and 14 connected by a top cross passage 15, three intermediate cross passagesl. and a bottom cross passage 17,3 while the sections are placed in communication witli each 'other by means of upper and lower headers 1S and 19 formed by abutting annular projections 20 extending from each face. of each section respectively at one upper corner of the section and .at the lower corner of the section disposed diagonally therefrom. Each jointbetween adjacent projections is rendered tight by means of a push nipple 21 received Within annular recesses 22 in the engaged projections 20. The

-forward end of the-header 18 is' closed by HEATING APPARATUS.

ingthat'end projection 20, whilethe rear ly engaging that end project-ion 20.l

Tl'ie'end' sections 12; are in turn flanked by a front end plate 27, provided with an aper- A 31, an'cl'a'rear'eiid plate 32, provided with an aperture 33v for the outlet duct 24 and van aperture 34 forthe inlet duct 26 "and an aperture (notl shown)` communicating with the interior of'the vent duct v35. f

'nachgefuis seasons; ligand `12 is' provided on onefsilde Iwith "an incomplete V)annular flange 36 Yn theother sidefvvitli a similar inconipltejannular an'ge J37 arranged to seat injvarlly fof the tlange A36to provide al staggered":passage which 'may be, readilyv closcdbyfsuitable iiiateri'al such as putty to thus'seal 'the gap between adjacent sections over that portion ofthe periphery of the sections 'suhtende'd the flanges 36 and 37', whereby such a seal' is provided with .sections all exactlynlike over thebody portion thereof? Thefront end plate 27 is provided with'a ange 38 similar to one of the flanges 37 and therefore arranged tol cooperate with thefflangef36 of the adjacent end section "'12'iv'hile theta-ear end "plate 32 is 'provided with .a flange 39 similar to one of the flanges 36 and therefore arranged to cooperate with the :flange 37 of the rear end element 12.

vThe space between sections remaining unsealed by the flanges 36, 37, 38, and 39 is normally closed by plates 40 each hung at its upper end from the two adjacent. sections 11 or12 or end plates 27 or 32 but removable to expose the spacebetween sect-ions to pernait cleaning thereof.

The vsections 11 and 12 and the end plates 27 and 32 are secured together by means of tie rods 41'l and 42 passing through apertures 43 and 44 inthe sections 11 and 12, apertures 45 and 4G in the front plate 27, and apertures 47 and 48 in the rear plate 32, and screw-threaded to receive nuts 49 engaging the/exterior facesof the end sections- 12 to hold the sections 11 and 12 firmly together, and nuts 50 engaging the exterior faces of the end plates 27 and 32 to hold these plates firmly in position against the sections 11 and 12. l

The'sections'yll and 12 andthe end plates 27 and'32a're`supported bylaterally pro-4 operating ,aperturestl 'in the supporting` ring 57. The sections 11 and 12, and the endplates`27 'and 32,'-are surrounded by an asbestos lined sheet metal casing con'iprising a cover lprovided Witha dependingy flange 62, a pair of 'sidepanels--and G1 held in.

' position lb'y-tlie flanges 62 of the cover 61 and atlange `tcarried-by the base plate 52, and a pairof 'end panels'66 and 67 held in positionbyfthese flanges 6 2v and G5 and also by the overhanging edges 68 of the side panels -63 and 64;." ,i'lhelijside-panels, 63y and 61 are cut away t o permit the lateral projection of thelegsSGanjdM', the vfront panel .66 is cut away'topermit einergelice ofthe thermostat 23 `and door` andaccess tothe burner aperturel 3Q, tandftherearrpanel Gt is apertured `for "the passage'bf the conduitsv 2t and. 26

and the vent-duct v35.. The side. panel 64 serves to maintain the plates. 40 closely in thesectionsfll and'12 andlen'd plates 27, and

32 yet at the same time is slightly shortened, whereby 'it-may be slid upwardly within the flange y62 of the cover 61 Va suflieien't distance to bring the loweredge of "thesidc panel 61 above thelto ot'the flange 65 of the base plate 52 tot ius permitready removal of the panel 64 for access to and removal of the cleaning plates 40.

The cross passages 16 in the sections 11 and l2 are lformed irregular in shape to baille the heating gases arising from the burner 31 fand the end plates 27 and 32 are provided With battles 69 arranged to cooperate'with the exteriorfaces of the cross vpassares :16 ot the end sections 12. The

location of the burner above the lower header 19 prevents the escape ot' heat downward and utilizes the heat thus ordinarily wasted to warm or preheat the fluid in the lower header 19 prior to its flow upwardly through the passages 13, 14, 15, and 16 of the scctions 11 and 12.

The tank portion B comprises' a tank which may bevof any suitable construction but is preferably of metal provided with a suitable covering o l heat insulated material. This tank 70 is provided with an intake conduit 71 connected to the supply main and extending to a point adjacent the bottom of the tank, an outlet conduit72 extending to the supplied system from the top of the tank, a cold circulatingiluid conduit 73 extending from the bottom of the tank to the intake 26, and a hot circulating fluid conduit 71': extending: from the heater portion outlet 21 to a point adjacent the top of the tank. The tank 70 is mounted. within a flange 75 on the supporting ringf and secured in that position by means of bolts, 79 passing throun'h apertures 76 in the. depending rim 77 ot the. tank 7() and thence through cooperating apertures 78 in the supporting ring ot. c i

The fuelleeihand control portion C. com-` prises a conduit 8O arranged to supplyfucl to .the burner 31, preferably interceptedby a pressure reducerI 8'1 designed to reduce the operating pressure below7 the minimum likely to exist in the supplymain. and then intercepted by a valve S2 controlled by the thermostat 2S. yl`he thermostat 23 and valve S2 arenot shown herein yin detail because these elements` do not in themselves forni any pai-tot my invention but may be of any suitable` construction whereby increase inv the temperature ot' thefluid sin-rounding the thermostat. tube 83' will reduce or shut off the supply of fuel lo the burner 31 and decrease ot temperature vin the -fluid adjacentv the thermostat tube 83 will increase or recomf nicncc the supply of fuel to the burner 31. In actual practice I have found satisfactory the thermostat manufactured by The Yoder- Thomas Manufacturing Companyof. Cleveland, Ohio. lV ith this thermostat Iutilize a pilot light supplied through a conduit Si which intercepts the main conduit S0 ahead ol the valve 82. y

lt will be apparent from the above description that I have provided a heater wherein the closing of the .spare between sections is facilitated and accomplished, the cleaning strips readily and firmly positioned, the` entire heatA utilized, thc tank `secured and supported in a novel and improved.manner, sufficientcapacity provided to permit the circulation of a large volume, oll fluid Vbetween the Aboiler and the tank, and the action o'f'the heater controlled by the ten1- perature oflhe fluid leavingV thehcater whereby the maximum temperature of the fluid may be predetermined and maintained below any critical temperature such as. in heatingr water, the ten'lpcrature at which inineral matter is deposited or chemical action induced. Those skilled in the art will rcadilylind additional advantages in the device herein illustrated and will also readily realize that the particular embodiment ot' my invent-ion hcrcinshown and described may bc variously changed and modilied without depart-innr from thc spirit of my invention or sacrificing the advantages thereof. It will therefore be apparent that this disclosure is illustrative only and that my invention is' not limited thereto.
